Abstract
Systems and methods for efficiently encoding and/or reformatting video data including transparent overlay portions are disclosed. In one embodiment, the method includes using two prediction regions for predicting the portion of the video including the transparent overlay. In one embodiment, a first of the two prediction regions is determined based on motion compensated prediction in reference to another video frame and a second of the two prediction regions is a collocated portion of video in another frame as referenced by a virtual zero motion vector. A mixing weight factor to be used for combining the two predictions is determined. In one embodiment, the mixing weight factor is determined based on the relative values of two error metrics, a first error metric related to the motion compensated prediction and a second error metric related to the collocated prediction of the virtual zero motion vector.
